Hi guys and gals !
So a few days ago i rooted/flashed my friends s5830 regular way and uploaded VillainRom, yesterday he came by my house for he has tried to upload LucaRomv2 by using Rom Manager.
As a result the phone stays dead at "Samsung" logo on regular boot, altough if we plug it in the pc it will detect the modem, sd card(not acessing it for it must have usb debugging enabled) and all, just the screen that doesnt pass "Samsung" logo.
So the logical next step is if we have communication is to press the magic buttons VOL- + Home + power ON, and it does work for it goes to download mode, the only problem is has soon has i plug it on my VM (VBox 4.0) it just spits out usb error on VBox and does not connect.
I have tried all combinations Volume+ (flash mode) all enters, its just that when i plug it to VM it spits out an error.
I can even enter recovery mode by HOME+POWER (and for the looks of the register that show when i enter it it complains it cant find /data, /cache .... so my guess is Bootloader is still ok has it enters all these modes and just need to re-upload rom(basically the os)
So leading to usb error in VM i prompted to fully test my VMUSB everything works ok connecting it (storage drive, my vodafone smart, usb cam) and even the s5830 itself while on regular usb connection. This has worked ok before for this is the computer/vm i used it to flash it originally.
Just to relief up i will try the following today:
Clean format a physical computer with winxp and try do the process without VM in the middle
Should i make the usb jig with 301K ? Has anyone actually tried usb jig on ace ? Whats different from this mode to regular vol- + home + power ? From what it seems its factory download mode i guess, an alternative bloader.
In case of JTAG needed does anyone have flash specs ? I mean offsets and such ... i have access to JTAG tools here at work, just a matter of pinout and see if cpu/flash supported.
What is your general opinion about this ?
I have launched this thread for i have not found any info on this kind of situation, people usually have fully bricked (black screen) or can still access download mode and communicate with pc, i have not found similar characteristics.
Thank you !!
Did your friend a wipe after flashing the rom? If not then go to recovery and wipe Dalvik cache - cache and Data/factory reset.
If this doesn't work put the phone in Download Mode and flash with Odin and after this make a wipe.

steini81: I dont know exactly what he did, i have tried to wipe it via recovery manager but still no go, it still complains on missing mounts /data /cache .... as for flashing with odin i can start download mode on the phone but has soon has i connect it on the usb port of the computer it just gives out an error and does not go online.
Lovetz: I already read that post, the difference is i still can go to download mode, my problem is when i plug on pc it doesn´t go thats why i opened another thread.
--------------------------------
Maybe it´s just Virtualbox playing it´s pranks with async usb, can only eliminate this chance later on for i dont have the sga with me.
how about using a different machine? a machine with the drivers from Kies..
Try it on a Windows PC with Odin and Kies Drivers installed.

Mundix: I´m already using skeys drivers, tried killing processes and not killing them, but this subject goes further then that because i think i have usb connectivity issues, now, it worked ok when i first flashed this device maybe something corrupted my usb1/2 modules for virtualbox (btw running debain squeeze-> virtualbox -> xpsp3, with full usb 2.0 extension loaded (already tried only usb 1.0 only has it has helped before on the first flash). Plus all usb devices work ok, including the samsung itself on "normal" boot so i dont know, maybe has its a raw dump vbox doesnt like it Later on i will format a computer with xpsp3, load skeys, odin and start from there,so basically you agree with my point
Steini81: yeps thats what im gonna do, but i do not use any windows machines all obsd/debian at home and work so ... only virtual, i´ll grab an old borrowed laptop and format it just for this.
-------------------------
Once again i just opened the thread because i havent found anyone with same situation, either its fully bricked or they can usb plugin. No post until now for usb download mode crash. I will follow up here maybe it might help someone in the future, or will confirm brick altough bloader boots and phone detected on "normal" mode.

My sister's Backflip had a similar issue . All I did was to wipe EVERYTHING then reflash .

SOLVED !
1 st Run:
Clean XPSP3 *Laptop* - "Unrecognized USB device ...", exactly has ocurring in VM.
No go.
2 nd Run:
USB JIG (tried 299K, 300K, 301K and 302K accurate resistors 1% tolerance) followed by above method.
No go.
3 rd Run:
Load WIN7PRO on a desktop for s-kies was giving problems with framework4 on XPSP3.
No go. "Unrecognized usb ..." just like on the laptop with XPSP3
Thats when it hit me, "some" devices(MODEM, STORAGE) load ok, odin driver does not, so it does have partial usb communication, this made me go way back in time when i had a USB MSI WIFI that would only work stable under USB 1.0 and was buggy under 2.0, so ...
Step 1 - Take the dust out that powered USB 1.0 Hub from drawer;
Step 2 - Make pigtail from internal desktop 12Vcc to power usb hub for Vcc stability
for power supply been lost like 4 house moves ago(yes i could go external powerless but ... just in case);
Step 3 - Cook a good home meal and mix it with some fine red wine;
Step 4 - Hook up usb hub, let win7 install, hook up SGA while on DOWNLOAD MODE (Vol- + Home + Power) and you can have the batery installed, no need to hot plug it, connect to usb hub.
Step 5 - Be amazed has it detects "Odin" has a new device and Odin square turns yellow just waiting for you to press start ...
*Personal Note : Do not stand up quickly after step 3 !
Now, the funny thing is if i move the USB 1.0 HUB to the XP SP3 Laptop its also a go, same results for in my Virtualbox install. Notice i tried it on 2 physical/1 virtual computer under VBOX4.
In conclusion:
If your SGA still boots to "samsung" and lets you get in Download/Flash/Recovery but gives out an USB communication errors, but still installs some devices like MODEM/Storage, all of this after a run from ROM MANAGER, please *DO* try to put an usb 1.0 hub between your computer and your SGA.
At this moment it works like a charm and i´ve just uploaded coderom.v2x-02, altough if i remove the USB HUB its back on the same problem, trough the hub it works ok aside i have 1.0 transfer speeds ...
Now, some help on debugging, arent there any logs on the system i could analyse? Should i dump trough JTAG ? What could of happened so that it has this symptom now ?
Anyways thanks for those who tried to help, just hope this helps someone in the future !
Hi all.
I received my prestigio pmp 5297c with 4.2 preinstalled. I tried to find a way to root it but without any success.
Any idea would be valuable.
Thanks.

Hi,
I found a solution thanks to this web site:
http://androidforum.cz/viewtopic.php?f=815&t=48237
Translate it with google translate to english. I had some problems installing the right driver on my windows 7 x64 machine but I succeeded.
Basically it goes like this:
1. Download the zip from the link on the web page and unpack it.
2. Start the RKAndroidTool.exe (in the status bar it will say "No found RKAndroid rock usb")
3. Shut down your tablet and disconect the usb cable from the tablet that is connected to your pc.
4. Press the volume up button and hold it for 6 - 7 secconds.
5. Still holding the volume up button plug in the usb cable that is connected to You pc. (At this point in my case nothing happened)
6. (If nothing happens) Go to control panel - device manager and there You will see an unknown device.
7. Right click on the unknown device and select update driver. Point to the folder where You unpacked the downloaded zip / Drivers folder and select the search in subfolders checkbox. press OK button. Windows will install the drivers. After that if the tablet didn't start automatically boot it up by pressing the power button.
8. The RKAndroidTool.exe now will recognize the device.
9. Set the checkbox next to rom/recovery.img and press "RUN"
10. The tool will do what it has to do.
From here on just follow the instructions for rooting the tablet from the website.
Hope it will work for You as it worked for me.
Regards
Just use King root from Play Store
Hey guys,
Recently I ordered the Allwinner A13 (Q88) from DealExtreme. I wanted to flash a custom ROM onto it, but following all the guides I still can't manage to get it. First of all, I noticed that the firmware it came is 4.2.2 Jelly Bean, as opposed to 4.1 as they had written on the site. Anyways, I managed to get the storage drivers (computer can see the device and I can put files onto it), but I'm not sure about ADB, because the computer says nothing when I connect it in debug mode and it just makes a noise that a USB device is connected. I tried using LiveSuit to flash it, and after watching some guides that tell you to hold down the volume + key and press the power button 6 times, I found out it only works when I hold down the power button, and even when I do that it says that the USB device is not regognized (error 43). I have Windows 8.1, but I tried to do the same thing on my Vista laptop, and after I do that there, it connects and disconnects, and says that the device was unplugged. I wanted to know, how can I flash it? Is it a driver problem or the tablet is just faulty in that matter? I tried using Uberizer and that doesn't find my device as well. I would really be thankful if someone could help me out, because I want to install a custom ROM. Thanks!
Have you tried the Tech Know forums : http://www.techknow.me/forum/index.php?board=130.0 ? They are quite resourceful when it comes to cheap tablets or devices.
Hi all, I will try to be as detailed as possible.
I have a MetroPCS LG MS323 which I bought as a second phone to use when I travel as my regular phone is CDMA and I wanted a GSM phone that I could use with a sim card. While on an overseas trip I paid a cellphone place to unlock the phone so I could use other carriers' sim card, it was working fine since then. However, as I don't use the phone on a regular basis it ended up sitting and the battery lost its charge. When I tried to charge it by usb, it started bootlooping (vibrate, LG logo, repeat). After that I pulled the battery and charged it using an external charger. The phone is not rooted. I tried the factory reset key combo, but it gets stuck on the screen which says factory reset processing........ endlessly. I tried to download kdz file and flash with LG flash tool but phone cannot get into download mode. When I press vol key and plug usb cable, it says LOADING.......... press volum up key until download mode starts But it gets stuck there and download mode never starts.
I downloaded adb and fastboot to a Windows 7 laptop, and LG drivers, but when I connect phone and open a terminal adb devices shows no phone connected.
I also downloaded Laf.img for this phone and Laf recovery tool for Windows but again I cannot seem to get computer to see the phone. If I try to use the tool it says "waiting for device"
One difficulty is to trying to plug phone to computer the right way.
Most of the threads say to have phone in battery charge mode with usb debugging enabled, but I can't select any settings if the phone is bricked.
If I just plug the phone to usb when it is turned off it shows a picture of battery but no sign of charging, and computer doesn't detect phone.
If I plug phone to usb first, then hold vol and power key the LG logo will go black and it vibrates, in that case sometimes the Windows laptop will see 2 folders, verinfo and image.
When I plug usb cable to Linux computer and phone is off, same thing just picture of battery but terminal only shows sda1 sda2 sda3 etc no sdb no sdc just like not detected.
If I hold vol down then plug usb it vibrates and stuck on LG logo.
I have also tried to plug usb, then press vol down and power until phone vibrates, then try to let go buttons before LG logo shows up. but it doesn't mount.
If I hold vol up and power, then plug usb. it vibrates and goes to LG logo.
Last night somehow I got it to mount on the linux computer but the file manager was going crazy opening multiple windows and a list of folders would show up for a second, disappear and reappear as if the system was trying to read the folders but having difficulty. Today I am not able to get it to mount.
I have downloaded a linux livecd with adb and fastboot, I haven't tried it yet because I am not sure the path to flash an img file from a different directory on the hard drive on the windows laptop.
I have downloaded aboot.img but don't know how I can flash it if I can't see the phone on any computers.
I have spent days searching for solutions but have not seen the exact same problem, other threads suggest things but often the symptoms are slightly different or with a different phone. So, first of all I need to know what kind of brick I have, because other solutions I have seen posted for completely black screen, or phone detected as qhsusb qualcomm etc. which seems like a different problem.
So the 2 main things are 1, to know which kind of brick because many of the solutions I see posted seem like a different problem.
second, what is the best way to plug to computer so I can see the phone?
I burned a live CD of FWUL and ran adb from linux, still says adb devices nothing shows up. usb cable is plugged in and phone is turned off. Am I doing this wrong? I held down power and vol down until phone vibrates and LG logo appears. adb devices - "list of devices attached" still has nothing showing.. I don't know why even in Linux I can't see any device attached. Also I tried with pressing vol up and power until phone vibrates.
ls /dev/sd* only shows sda sda1 sda2 etc
I have also looked at past threads about unlocking the L70 bootloader, but the bootloader.zip no longer links and the phone does not have busybox installed.
I tried to see it Windows Device Manager but it does not show up anywhere.
This probably won't help, but, when you're at this point, you'll try about anything.
Did you fully install the LG drivers on your PC? Obvious seeming question. I was doing an old Droid Bionic a couple months ago and didnt' switch the USB modes (charging, media, file transfer, whatever it had) to each mode before modding .
As a result, I bricked that Droid bad. It took me almost a week and a half to restore it. I'm not sure if LG drivers work the same way, though I've worked on plenty of them. I think I have an LG Leon still in the scrap heap as a result of trying to replace a cracked digitizer that was bonded to the LCD. If anyone needs parts for one, I've got em, cheap I think that's an MS345 if I recall.

Thanks, yes I had installed latest LG drivers LGMobileDriver WHQL Ver 4.2.0 before trying to flash .kdz file.
A tiny bit of progress to report, after getting a perfect timing to release the power and vol down keys I was finally able to connect to Windows machine. while waiting for drivers to install it was detected as QHSUSB_BULK in device manager, after drivers loaded now it is listed as LGE AndroidNet USB Serial {port (COM4). However when I run adb I still cannot see an attached device. I will look at solutions for the specific type of brick problem which has now been identified.

What I meant was after initially installing the drivers did you switch the USB mode on your LG to all possible settings? Some drivers (like Moto) install more functions only when first called. you'll know if you switch from say charging to MTP or RNDIS you'll see driver install reopen.
also when you first ran ADB and plugged in the phone you probably should have seen more drivers install.
Forgive me if I seem to insult your intelligence. I'm an IT pro w 30 yrs in tech and I didn't know about the multi driver USB functions.
Tom Sgt aka Rootjunky has a good video on this that i initially didn't watch figuring I'd been installing drivers forever. 5 more minutes of watching it would have saved near 40 hrs of work and research

thanks, I found his video for the G2 and no, I have never seen that with the drivers before! good to know. You can't insult my intelligence because most of this is over my head and I'm just trying to follow stuff I found with Google on XDA......
I downloaded and installed the Qualcomm drivers to try and identify if I have the 9006 or 9008 variety brick. However now when I plug in the phone Windows waits to install drivers, then says successful, when I look in device manager now I can't find the phone. But I did notice on the taskbar now there appears an icon named "intel graphics media accelerator driver for mobile" perhaps that is the driver Windows assigned to it? Device manager does have Intel Graphics Media Accelerator under display adapters. The other weird thing is that now it shows the battery as charging, which it never did the other times I plugged it into usb.

it has the firmware for your model links to drivers and the LG flash tool, (which is warned against newbies (what the hey, it can't get much worse, we were all newbies once, )
Can you boot into fastboot? if so, you could flash the firmware with that.

Hi, yes although those links no longer work I have found the drivers and flashtool elsewhere. If I try to run flashtool it cannot see the phone. I cannot get into fastboot, and download mode won't load. I cannot see the phone on any Linux machine. The most I can do it see the phone as E: Qualcomm MMC storage USB device in Device Manager, but no other details. Explorer can see 2 folders, image and verinfo. Is there anything I can do with these folders in Windows? adb and fastboot run from terminal still do not list any attached device. Windows did a search for drivers for QHSUSB_BULK, although in device manager it still says LGE AndroidNet USB Serial Port (COM5).
What I really want to do at this point is push aboot.img to the phone, but for some reason I can't access the phone with Linux or adb. maybe because it did not have usb debugging enabled before it bricked. So many of the threads I have seen require a working phone to implement the steps, is there any way to enable usb debugging when the phone doesn't work?

Of course, I had forgotten about that. In order to use fastboot, most flashing tools, you HAVE to have USB debugging on.
There are occasional ways around this, though they are few. I do seem to recall oding it on that LG Leon. OR it may have been a Moto e or G, let me look back at previous threads i've asked for help in.
(Hmm, perhaps taking notes, or just leaving a webcam running while I'm doing a new device might be valuable in the future, I think with remarkable hindsight.) :cyclops:

And no, you can't do anything to Android files in Windows, except see them. they are generally a different file system
One of the difficulties is just plugging it to a PC. 9 out of 10 times it is not recognized and nothing happens. So far the only way that seems to occasionally work is to plug the usb cable to the Windows 7 laptop, hold vol down and power, release both as soon as it vibrates. Most of the time I can't get it timed exactly right, but if I'm lucky sometimes Windows will detect the usb connection by following these steps. If I try on a Linux machine nothing happens, phone stays invisible. The most I've gotten with Linux is to charge the battery, but will not mount.
It is just a stock phone, not rooted, no busybox, no developer options enabled.
